What a difference the day makes. When we were there, the German restaurant was the picture of idyllic tranquility, just a couple of tables of people sipping (very cold) beer and watching the birds and the river. The potato pancakes were fabulous. I don't know if people are suggesting eating on the boat, but the boats can get very full, and it would be like having a picnic on the #60 bus. Also, be careful about going out a long way and getting off because the more remote you go, the less frequent is the return service. It could be a very long day.
